A magnitude 2.4 earthquake was recorded 27 km (16 mi) E of Honaunau-Napoopoo, HI, at 8:33 am HST on 7 October 2026 (18:33 UTC). This was a minor earthquake. Quakes this small are rarely felt and do not cause damage.

At this magnitude and depth it was probably too small to be felt, even directly above it. In Honaunau-Napoopoo, 27 km away, the estimate is intensity II (weak). Estimated from magnitude, depth and distance with the intensity equation USGS Did You Feel It? uses; felt reports, where there are any, are the measurement.

How big was it?

This earthquake released about 110 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 3.4 would have released about 32 times as much.

Mineral, Virginia 2011 M 5.8 130,000× the energy of this one
Magna, Utah 2020 M 5.7 95,000× the energy of this one
Around the size people start to feel M 3.0 8.5× the energy of this one
This earthquake M 2.4 about 110 lb of TNT

Energy from the Gutenberg–Richter relation (log₁₀E = 1.5M + 4.8), rounded to two figures; bar length is magnitude, which is already a logarithm of energy. Magnitudes of past earthquakes from the USGS catalogue.

For this area

The largest earthquake within 50 km since 2016 was M 6.0 on 2026-05-23 — about 230,000 times the energy of this one.

Before 2016, the USGS record lists 34 earthquakes of M5 or more within 50 km; the five largest:

6.7 22 km W of Volcano, Hawaii · 17 km E of this epicentre Nov 16, 1983
6.4 Kaoiki area, Hawaii · 23 km E of this epicentre Mar 28, 1915
6.3 20 km SSW of Honaunau-Napoopoo, Hawaii · 35 km WSW of this epicentre Aug 21, 1951
6.2 8 km SW of Volcano, Hawaii · 33 km E of this epicentre Nov 2, 1918
6.2 21 km N of Pahala, Hawaii · 18 km E of this epicentre Jun 28, 1962

Since 2016: the QuakeIndex catalogue (US, M1.5+), built from the USGS FDSN event service. Before 2016: USGS ComCat, M5+ from 1900. Distances are between epicentres. This is the record, not a forecast.
